I am not sure about other models but the one I find worth buying is HK597. It is a 4 channel amp that's 200W rms at 4 ohms, 400W rms at 2 ohms per channel. I am currently using MA Audio's 18" sub. It is wicked.
well i can get the kicker kx850 for about $230 and the rockford fosgate 850 for about $220. I have just had alot of experiece with the chrome amps in my day lol. They just dont perform as good as products that the pros or semi pros use.
Hey Joseph, that kicker amp is a nice one but only one problem. It's a 2 channel amp. The MA Audio was 4 channel at 400W rms x 4 at 2 ohms. If you could get that for $230, it's a great deal. Some are charging $600! I wouldn't try any other MA model except HK597.
